Yeah man, why not disengage your already inadequate forces from the major cities that you already can't defend, cut your own lines of communication by manuevering behind enemy lines, and embark on what has to be over a thousand mile flank march with utter contempt for the enemy's superior air assets and without any serious AAA, armor, or counter-battery assets. And this brilliant end run can definitely be supported logistically. You definitely won't run out of fuel and spare parts a quarter of the way there and be sectioned off and decimated piecemeal.
